Screaming at your teenagers to discipline them can make their behavior worse - even if you otherwise have a warm family relationship, researchers say. The effects were comparable to those in studies that focused on physical punishments, the researchers said. “From that we can infer that these results will last the same way that the effects of physical discipline do,” the lead researcher, Ming-Te Wang, an assistant professor of psychology in education at the University of Pittsburgh, said in a statement.

Up and down the West Coast, starfish are dying. Casualties of a mysterious disease known as seastar wasting syndrome, they are dying in Alaska, deteriorating in San Diego and disappearing from long stretches in between. Death from the disease is quick and icky. It begins with a small lesion on a starfish's body that rapidly develops into an infection the animal cannot fight. Over the course of the disease the starfish's legs might drop off, or even separate from the body and start to crawl away, as you can see in the PBS news story below.

The dark dust thrown up by human activity in the deserts of the Southwest hastens the melting of Rocky Mountain snow and ultimately reduces the amount of water flowing into the upper Colorado River by about 5%, scientists reported Monday. The lost water amounts to more than 250 billion gallons — enough to supply the Los Angeles region for 18 months, said study leader Thomas H. Painter, a snow hydrologist at the Jet Propulsion Laboratory in La Cañada Flintridge. "That's a lot of water," said Painter, whose study was published online by the Proceedings of the National Academy of Sciences.

Two rare, ribbon-like fish that washed up on Southern California beaches last week have puzzled and excited scientists, who know little about the creature that inspired sea serpent lore. The oarfish, deep-sea dwellers that remain largely mysterious to researchers, have been seen underwater only a handful of times. What is known comes from the few carcasses that have washed ashore. "If all you knew about deer was road kill … how much would you actually know about deer?" said Milton Love, a research biologist at the Marine Science Institute at UC Santa Barbara.

A rice-eating chicken has laid a giant egg weighing nearly half a pound. Unfortunately for Easter-egg-painting Americans, the chicken is in Guizhou, in southwestern China. The fowl's owner told the media that the hen began laying the eggs about a week ago. When it struggled to lay its first gigantic egg, "she thought the hen was dying. " Now it has laid several such beastly eggs. When villagers cracked open one of the latest, they found two yolks inside - and another regular-sized egg. They cracked that one open and found ... no new surprises, thank goodness. The owner said the only thing that distinguished this hen from her others was its diet.

According to the conventional wisdom that liberals accept climate change and conservatives don't, Kerry Emanuel is an oxymoron. Emanuel sees himself as a conservative. He believes marriage is between a man and a woman. He backs a strong military. He almost always votes Republican and admires Ronald Reagan. Emanuel is also a highly regarded professor of atmospheric science at MIT. And based on his work on hurricanes and the research of his peers, Emanuel has concluded that the scientific data show a powerful link between greenhouse gas emissions and climate change.

What if the solution to smog was right where the rubber meets the road? Scientists in the Netherlands have found that installing special air-purifying pavement on city streets can cut air pollution nearly in half. Researchers at Eindhoven University of Technology outfitted one block in the city of Hengelo, Netherlands, with paving blocks sprayed with titanium oxide, which has the ability to remove pollutants from the air and turn them into less harmful chemicals. The researchers left normal pavement on an adjacent street as a control.

A team of storm-chasing scientists sampling rarefied air has found a world of bacteria and fungi floating about 30,000 feet above Earth. The findings, detailed Monday in the Proceedings of the National Academy of Sciences, suggest that microbes have the potential to affect the weather. Scientists have long studied airborne bacteria, but they typically do so from the ground, often trekking to mountain peaks to examine microbes in fresh snow. Beyond that, they don't know much about the number and diversity of floating microbes, said study coauthor Athanasios Nenes, an atmospheric scientist at Georgia Tech.

Famed physicist Stephen Hawking set off chatter in the scientific community in late April when he posited the existence of intelligent aliens on his new TV series, "Into the Universe with Stephen Hawking" —adding that it would be best for human beings to avoid contact with them. Hawking speculated that such aliens would likely be nomads, living in ships after sucking their own planet dry of resources, and hopping from one interstellar refueling station to the next. Earth, he said, shouldn't do anything to encourage their visit.

The catch of small, schooling fish such as sardines and anchovies should be cut in half globally and the amount left in the ocean doubled to protect the ecologically vital species from collapse, scientists say in a new report. The silvery species known as forage fish are harvested in huge numbers worldwide and are easy for fishermen to round up because they form dense schools, or "bait balls. " But wide fluctuations in their numbers make them especially vulnerable to overfishing, according to the report released Sunday by the Lenfest Forage Fish Task Force, a 13-member panel of scientists from around the world.
